Starting Frequency - Mitsubishi Electric FR-CS82S-025 Instruction Manual

Parameters referred to
Pr.1 Maximum frequency, Pr.18 High speed maximum frequency
Pr.7 Acceleration time, Pr.8 Deceleration time, Pr.44 Second acceleration/deceleration time, Pr.45 Second deceleration time
Pr.178 to Pr.182 (Input terminal function selection)
5.4.4

Starting frequency

It is possible to set the starting frequency.
Set this function when a starting torque is needed or the motor drive at start needs smoothing.

Starting frequency
F102
 Starting frequency setting (Pr.13)
• The frequency at start can be set in the range of 0 to 60 Hz.
• Set the starting frequency at which the start signal is turned ON.

NOTE
• The inverter does not start if the frequency setting signal has a value lower than that of Pr.13.
For example, while Pr.13 = 5 Hz, the inverter output starts when the frequency setting signal reaches 5 Hz.
CAUTION
• Note that when is set to any value equal to or lower than
Pr.13
